Trio8800 Skype USB Optimized Mode


I've seen Polycom Youtube videos and many articles of using the Trio8800 as a Microphone and Speaker in a meeting room.

I am trying to use it with Zoom as a table speaker/mic

I have turned on USB Optimized Mode and connected via USB

The PC detects it as a USB device, Mic & Speaker


BUT - The phone will not boot up unless is finds a DHCP IP Address, I tried entering a static address but then complains about Time/date out of sync

I don't need to connect to any telephony system, just act like a audio device


Any way around this problem?

Hello @sherlockab,

welcome to the Polycom Community.

It is always useful to include the currently used UC Software version as issues experienced or a question asked may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Must Read First" and is the absolute minimum requirement every new post should include. .

In addition providing us with this basic information gives Polycom an idea what Software Versions are used in the field and avoids wasting time trying to troubleshoot issues which have already been addressed.

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP or UC Software Version of my Phone?
Resolution: Please check here


The latest UC Software 5.7.1 added a dedicated Zoom Application and is the recommended way to connect to Zoom.
